Determining the Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.


Bolt Pattern - Even

On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)


Bolt Pattern - Odd

To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)


Bolt Pattern - Side

Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

  • If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
  • If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
  • If D = 3", then the bolt pattern is 5 on 5"
  • If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

  • Correct Spindle for Hub with L44610 and L68111 Races
    The numbers that you mentioned are actually for the races that pair with the inner and outer bearings in the trailer hub. The # L44610 race is commonly used with the # L68149 inner bearing while the # L68111 race is usually paired with the # L44649 outer bearing. If this is the case then you likely have a 3,500 pound hub like the Dexter # 84546UC3 that is compatible with a #84 spindle like the TruRyde #84 Spindle, part # TRU24FR. As long as you have a 2-3/8 inch round axle the correct...

  • Parts Needed to Install Trailer Brakes on a Load Rite Trailer Model UT6512
    Looks like your Load Rite trailer UT6512 has a 3,500 lb axle. Most likely it's a standard 3,500 lb trailer axle but first you have to check to see if the axle has brake mounting flanges. If you can get back to me with whether or not you have brake flanges and the brand of your axle (most likely Lippert or Dexter) I can see which kit we have that may work. Check out the link I attached to see a guide to use for adding brakes to your trailer.

  • What Dexter Brakes and Hubs do I Need for My 3,900 Pound Torflex Axle on 2020 Lance Camper?
    Hello Matthew, It would be nice if they could just stick with the basics like 2k, 3,500K, 5,200K and so on. Dexter Nev-R-Adjust Electric Trailer Brakes - 10" - Left/Right Hand Assemblies - 4.4K # K23-478-479 are the right brakes for your application. For hubs you can go with the Dexter Trailer Hub and Drum Assembly for 3,500-lb Axles - 10" Diameter - 5 on 4-1/2 # 84546UC3, or if you wanted to save a couple of bucks our etrailer hubs # AKHD-545-35-EZ-K.

  • Is Brake Controller Needed to Stop Trailer with Electric Brakes
    We have everything you'll need to add brakes to your cargo trailer but since we don't know exactly what axles you have you'll have to check out your setup and take a few measurements to determine what exactly you'd need to install everything. We actually have a guide that walks you through this entire process as well that I have attached to this page. You will need a brake controller to activate the trailer brakes like you mentioned. A controller allows you to modulate how much voltage...

  • Looking For Replacement Hubs For 2016 Trailstar Tandem Axle Boat Trailer
    Hello Tyler, thanks for reaching out. We should have a hub that will work for you, but unfortunately hubs require either knowing your bearings or precise measurements since they aren't universal. A 2,960 lb axle is also not common/standard. To find your bearings, you just need to take it apart and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you can't make out the numbers, you need to use digital caliper...

  • Parts Needed to Upgrade Trailer with 10 inch Hydraulic Brakes to 10 inch Electric Brakes
    The brake assemblies that will fit your axle and also are what I recommend is the kit part # AKEBRK-35-SA which are self adjusting and the correct size and rating. Your current drums will not need to be replaced. You can keep using your current coupler by either running a bolt through the sliding portion or welding it so that it no longer moves. To upgrade the 4-way of your trailer to a 7-way you'd want the upgrade kit part # HS381-9000 plus 10 gauge wire for the brake assemblies like...

  • Replacement Hub Components for Hub 9606020
    While the # L68149 most likely corresponds to the inner bearing number of your hubs. If this is the case, you have either a 3.5k or a 4.4k axle. In order to know absolutely sure, you need to know the corresponding outer bearing number or the inner and outer diameter of the grease seal. You most likely need to wipe away the grease in order to reveal the outer bearing number. In order to accomplish this, I recommend using calipers like the 4" Carbon Fiber Digital Caliper # PTW80157.

    We do have the regular Dexter Axle brakes and their Nev-R-Adjust equivalents. The regular (manually adjusted) brakes that you are wanting are listed as part # 23-26 for the Left Hand side and part # 23-27 for the Right Hand side. Their Nev-R-Adjust equivalents are parts # 23-468 and # 23-469 respectively.

  • Replacement Axle Spindle for Dexter P21-SLR with 76 Inch Spring Seats and 44649 and 68149 Bearings
    I reached out to Dexter and they no longer make that axle. I can confirm based on the bearing sizes you gave that you have a 3,500 lb capacity. If you determine you just want to replace the hub, I recommend the Trailer Hub and Drum Assembly for 3,500-lb Axles - 10" Diameter - 5 on 4-1/2 # 84546UC3 or # AKHD-545-35-EZ-K if you have the grease zerk integrated in the spindle. Since we can't match the spring seat to spring seat dimensions if you want to replace your axle I recommend using...

  • Brake Mounting Flange Recommendation for Dexter 3,500 lb Axle
    Looks like you have a 3,500 lb Dexter axle without brake flanges. The correct brake flanges for that style of axle is the part # 4-35. Welding a mounting flange, possible item # 4-35, is a very precise installation. The flanges need to be installed square and concentric to the hub and drum assembly and each other. If the flange is installed incorrectly rapid brake lining wear, improper braking, trailer dog legging, bearing failure, rapid tire wear and, worst of all, weakening of the axle...

  • How to Determine the Correct Hub for My MacGregor Sailboat Trailer
    Determining the correct wheel bearings, seals or hubs for a trailer is normally done by using the existing inner and outer wheel bearing part numbers and grease seal part number. This is the only way to be sure that the correct parts are ordered. The bearing part numbers will ensure that you get the proper size and weight capacity parts for your application. When replacing the hub you will also need to be sure that you measure the wheel bolt pattern (see link) and, if the axle capacity...

  • How To Remove the Brake Drum If the Brakes Are Locked On a Reinell Boat Trailer
    A trailer hub and brake drum should be able to be removed by just sliding off the spindle after the castle nut is removed. The castle nut is located underneath the grease cap. The trailer brake should not be activated. If the brake is locked that must mean that there is pressure on that wheel cylinder keeping the brake shoes against the brake drum. I would first checked the surge coupler on your trailer to see if the master cylinder is stuck or if anything is wrong with the coupler that...

  • How to Add Electric Drum Brakes to a Top Hat Econo Angle Utility Trailer
    In order to install electric drum brakes on your Top Hat Econo Angle Utility Trailer you will need braking assemblies, hub/drums, a breakaway kit, and trailer wiring. For the braking assemblies, I recommend using the Dexter Nev-R-Adjust Electric Trailer Brake Kit part # 23-468-469 because they are self-adjusting which means you don't need to make continual adjustments for even pad wear. For the hubs/drums, I recommend using the Dexter Trailer Hub and Drum Assembly part # 84546UC3 because...

  • Options for Adding Electric Brakes to Trailer Axle without Brake Mounting Flanges
    If your trailer axle doesn't currently have brake mounting flanges you have a couple of options, one of which is to simply weld on flanges like you mentioned. A brake mounting flange needs to be welded perfectly square and concentric, which typically requires a special jig and a certified fabricator with experience in this type of application. This isn't a DIY project, as it's vital that it's done with precision so you don't have suspension issues on the trailer down the line. Finding...
